LEMSIR 800A Portable Car Jump Starter QDSP (up to 7.2L Gas or 5.5L Diesel)12V Jump Pack Auto Battery Booster Power Pack with Smart Jumper Cables

*Charged to full in about an hour after removing from package. 4 handy lights on the case indicate the amount of charge. Mine arrived at about 75%.*Packaging was good. There was no damage to the product or accessories and was easy to unpack.The Good:- Has an on/off switch. Can be good or bad depending on the user, but I appreciate knowing I can physically turn it off vs relying on the device to do it for me. Other similar car starters I own don't have this.- 2 USB-A (one which has a higher 2.1a output) and 1 USB-C ports for powering other devices like phones, iPods, portable gaming devices (Nintendo Switch, etc.), etc. The C port is used to charge the car starter, but can also be used as a power output. This is good, but to be fair, most similar car starters from other makers have the same ability to use the starter this way.- Fairly compact. Not heavy, but enough weight to not have that cheap feel.- Flashlight is bright (on par with a typical smartphone flashlight). Don't expect too much distance, but very good within 5-10 feet or so.- Easy to use. No issues connecting the cables to the starter or the battery terminals. Tested on a 2.2L gas engine that hasn't run in over a month. Didn't get it started on the first try (not surprised since the motor hasn't run recently), but got it going on the 2nd. Did it 3 more times afterward and started up like a charm with plenty of power to spare for more attempts.- Display on the cables connector shows available voltage.The Bad or Meh:- The cables could be a little longer. It's true they don't need to be as long as normal jumper cables since you can place the starter close to the battery, but there may be some scenarios where having another 6-12 inches of cable would be useful. I own 2 other starters, and this one's cables are the shortest.- Does not come with a storage case. The other two I own and many I've seen available come with cases for easy storage. I'll make do with a bag of some sort, but it would've been nice for it to come with one (seems like this is the standard with other similar products).- I'm skeptical this could start a larger V8 engine. I'd have to test to confirm this capability. I feel more comfortable taking their word for it with smaller engines. I'll update this review if I'm able to verify.- This product is by far not the most expensive in its class, but it may not be the best overall value either. Around the same time, I purchased another brand of car starter for $10 less, but it's 1200A, has similar or better performance, and came with a case.Overall:I recommend this car starter. I've confirmed it works reliably on smaller engines right out of the box. Feels like good quality and includes some features available on most other car starters (flashlight, charge other devices, etc.). Not overly expensive.I can't speak for long-term reliability yet, doesn't include a case, cables could stand to be a little longer, and you may be able to find a better value car starter elsewhere if you do some shopping around.

I've had this battery pack/car jumper kit for almost a month and have used it for so much more than just a jump start for a vehicle. The compact size makes this battery pack ideal for travel! I originally bought this to put in our 4x4 off roading vehicle as a back up safety measure if ever we needed a jump, which one of our fellow off roading friends actually did need a jump and we were able to get their vehicle started and back on the trails in no time at all with this surprisingly powerful yet super compact battery pack! But, I have to admit we have used this battery pack for so many other uses that it now travels with us where ever we go, when we flew to visit family we were able to keep our tablet, and smart phones charged for the duration of our flight! The lasting power of one single charge varies on what you charge but it has done everything we've needed it to. When we go camping we plug our portable bluetooth speaker into it and play music for hours before the pack needs to be recharged. Overall the design and quality of this battery pack with car jumper cable attachments and USB to type C adapter cables included has far exceeded my expectations, and I would recommend this set up for everyone. Plus the packaging it comes in is super convenient for storing it as the box has a magnetic closure keeping all the cables and battery pack nice and organized. This would make a fantastic gift as well!

I ordered this a few months ago after recreated attempts using regular jumper cables failed and having to call my auto insurance road service the guy who came had one similar he hooked it up and immediately started my vehicle. I was so impressed I started looking for one and based on reviews ordered the Lemsir. I haven't had to use it yet but love how portable it is and the quality.I have recommended it to my daughter's so if they are ever stranded alone they won't have to wait for assistance and being able to charge your phone is definitely a plus!!

I will keep this in my car and boat. The battery and the accessories that come with it are well built. I know that this battery jumper will come in handy on land and water. I jumped many cars this winter and have towed numerous boats in the summer due to dead batteries. This little jump starter is perfect.

I thought I was charging it properly and was wondering why the light wasn’t filling up to full charge. Found out later that the charging cable that came with it was a dud so I used my own. Finally tried it today to jumpstart my cars. Full dead battery could barely set the alarm off and definitely didn’t start the car. (V8 4.6l). Went from 4 lights charged to one without even cranking it. Tried it again on my other car with a dying battery but only one light left. Enough juice to set the alarm off and crank but one light (<25%) wasn’t enough to crank it long enough. Recharging it right now to try it again later. We’ll see and I’ll update accordingly. The packaging and shipping speed was on point. But everything else is yet to impress me.

Great product. Started an 08 hummer h2 without a problem!! Highly recommend

This is just what we were looking for. Love the small size, and the relief of having it readily available should we need it. Anyone owning a battery over four years old should consider this item. The flash light and USB ports are added bonuses.
